Interpretation:
The factor that favors the formation of II product in preference to III from trans-decalin derivative is to be determined.
Concept introduction:
Decalin is a colorless liquid with an
The molar mass of decalin is 138.25 g/mol.
If the steric hindrance in a compound is less, then the stability of the product is more.
Steric hindrance of a product increases because of the presence of more bulky groups at the same position.
In double bond or cyclic compounds, if two same
If the two functional groups are present on the different sides of the double bond or cyclic compound, the given compound can be labeled as Trans.
